IMPROVEMENT IN PUDDLINGFFURNACES.

Specification formingpart of Letters Patent No. 122,731, dated January 16, 1872.

To all whom it may concern:

Beit known that I, DAVID MORGAN,of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and valuable Improvement in Puddling-Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part ot' this specification, and to the letters and figures of reference marked'thereon.

Figure l of the drawing is a plan view of my invention. Fig. 2 is a horizontal section ofthe saine.

' This invention has rela-tion to an improvement in iron puddling-furnaces; and the novelty consists in providing the bridge walls which inclose the lozenge-shaped hearth with a i number of sepa-rate water-boxes supplied from a tank by communicating pipes and provided with discharge openings to empty their contents into the bosh. The object of this improvement is the protection oi' the hearth walls from fusion by keeping the ore and scrap iix as cool as possible; and it tends to accomplish the purpose in view by allowing the water to be readily changed when its temperature or evaporation requires it. By the arrangement of separate boxes an advantage results from the fact that the repair of any part of the waterback does not necessitate the complete destruction of the furnace.

Referring to the drawing, A represents the furnace-casing; B, the puddling-hearth arranged within the lozenge-shaped inclosure formed by the hearth walls b. C represents the water-box within the :tire-bridge wall; D,

the water-box Within the flue-bridge wall; E, the water-box within the back wall; F, the

water-box within the bridge-j amb; G, the waterbox Within the iiue-jamb. c d e f g represent respectively inlet-tubes communicating with the water-boxes from a Water-tank, H, on top of the furnace. c d ef g represent outlettubes communicating with the furnace bosh from the Water-boxes, and designed for the discharge of their contents. All the inlettubes are furnished with stop-cocks by which to regulate the supply of water to the boxes. These boxes may be made either of cast or wrought-iron, are readily ada-pted to their positions, and by means of them a constant iiow of water may be kept up during the puddling process. They may be supplied according to their positions and other circumstances, and when one is damaged it may be replaced Without the necessity of displacing the other.

The inlet and outlet tubes enter the boxes from the outside extending thence around to their proper points.

I claim as my invention- In an iron puddling-furnace, the water-boxes C D E F G separately constructed and arranged around the hearth B, as described in combination with their respective inlet and outlet tubes andthe water-tank H, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence oi two witnesses.

DAVID MORGAN.
